Client Side: Using SIDL Classes and Methods
</H1>
<P>
SIDL's object model is very similar to Java's, and therefore maps
easily into Java's object model. A SIDL object is treated almost exactly the
same in Java as any other Java object, the only difference being that all data
held by the object is private, and all methods are public.
<P>
Importing SIDL packages and classes is also exactly the same as in
Java. For example, assume there is a package <TT>test</TT> that includes
the class <TT>HelloWorld</TT>, and you wish to print this message in
your program. The following code segment does this.
<P>
<BR>
<PRE CLASS="verbatim">import test.HelloWorld;
public static main(String args[]) {
HelloWorld hi = new HelloWorld();
hi.printMsg();
}
</PRE></td></tr></table></blockquote>
<P>
Writing the fully qualified class name would also have sufficed.
<TT>test.HelloWorld hi = new test.HelloWorld()</TT>
<P>
Babel also generates Java code in line with Java's use of directories
to organize packages and classes as files. For example, assume you
are generating babel code in a directory named <TT>babelcode</TT>.
Assume your package <TT>test</TT> contains 2
classes <TT>HelloWorld</TT> and <TT>GoodbyeWorld</TT>. After running
<TT>babel -cJava test.sidl</TT> you will have a new directory in
<TT>babelcode</TT> named <TT>test</TT> which will contain 2
files, <TT>HelloWorld.java</TT> and
<TT>GoodbyeWorld.java</TT>. These classes will be accessible
from your Java program as long as <TT>babelcode</TT> is in your
<TT>CLASSPATH</TT>.
